with what i learned in geology the half semester i took it an eartquake hitting the same area more than once is not all thatcrazy, especially when some serious modification happens underground. another shake is kinda like earth is trying to lay all the pieces where they fit best- that first quake put some established shit in some akward positions.

It can happen anywhere in the next hundred to five hundred years. Some scientists say that our strange trend in weather maybe due to the weakening effects of the polar shift on the magnetic field of the Earth. It will most likely happen a long time from now, but it's quite possible to feel the effects of it now. Magnetic north has shifted already 15 degrees from true north.

Some believe it's supposed to happen in *this* decade, but I think the majority of scientists believe that it will happen between now and the next five hundred years. No one really knows. All we know is that the polar shift weakens the magnetic field and subjects us to the harmful particles emitted by the sun. That can easily cause a change in weather patterns. (even slight changes)
